• What is the cause and solution for SAP error message /PM0/ABQ_MIG_MSG119 - Application number &1 was assigned more than once ?

  The SAP error message /PM0/ABQ_MIG_MSG119 indicates that an application number has been assigned more than once in the context of a migration or data transfer process. This typically occurs in scenarios where data is being migrated from one system to another, and there are duplicate entries for application numbers.
  Cause:
  
  Duplicate Data: The most common cause is that the source data contains duplicate application numbers. This can happen if the data extraction process did not filter out duplicates or if the source system had inconsistencies.
  Incorrect Mapping: During the migration process, if the mapping of application numbers is not done correctly, it can lead to the same application number being assigned to multiple records.
  Data Integrity Issues: There may be underlying data integrity issues in the source system that need to be addressed before migration.
  
  Solution:
  
  
  Identify Duplicates: 
  
  Check the source data for duplicate application numbers. You can use SQL queries or data analysis tools to identify these duplicates.
  Example SQL query to find duplicates:
  SELECT application_number, COUNT(*)
  FROM your_table
  GROUP BY application_number
  HAVING COUNT(*) > 1;
  
  
  
  
  Resolve Duplicates: 
  
  Once duplicates are identified, you need to decide how to handle them. Options include:
  
  Merging records if they represent the same entity.
  Renumbering or reassigning application numbers if they are distinct but incorrectly duplicated.
  Deleting unnecessary duplicates if they are not needed.
  
  
  
  
  
  Review Migration Logic: 
  
  Ensure that the migration logic is correctly implemented to handle unique constraints. This may involve adjusting the mapping or transformation rules in your migration tool.
  
  
  
  Test Migration: 
  
  After resolving duplicates, perform a test migration to ensure that the issue is resolved and that no further duplicates are introduced.
  
  
  
  Consult Documentation: 
  
  Review SAP documentation related to the migration process you are using (e.g., SAP Data Services, SAP S/4HANA Migration Cockpit) for any specific guidelines or best practices.
  
  
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional guidance on handling application numbers during migration.
  Data Quality Tools: Consider using data quality tools to clean and validate your data before migration.
  Migration Strategy: Ensure that your overall migration strategy includes steps for data cleansing and validation to prevent similar issues in the future.
  
  By following these steps, you should be able to resolve the error and successfully complete your migration process.
